On Saturday, September 24 we attended the Tokyo Calling 2 event hosted by Breakfast Club Rally. Z Car Garage participated with a group of client cars and enjoyed a wonderful day of driving through the foothills of Northern California. The event also featured 200 Japanese classics and 90’s-era wonders to appreciate during the morning social gathering and rest stops. Enjoy our report with mega-photo gallery and video!

 
 

Breakfast Club Rally

 

The Breakfast Club Rally (BCR) started just over 2 years ago. What started out as a small group enjoying weekend drives blossomed into a full-on Cars and Coffee (still unofficial) meet just before rally participants head out according to run group. The monthly BCR is always free/open to all makes and I highly recommend it for anyone looking to enjoy the beautiful Northern California roads and scenery. You can see my previous BCR reports HERE!

 

The initial BCR Tokyo Calling event held back in March was a success. We did not want to miss this all-Japanese, mostly-vintage rally so I assembled a group of Z Car Garage clients and friends to participate in TC2. We left the shop at 6:30am heading to San Rafael, here is a preview of our cars:

 

Gary’s 1971 Datsun 240Z

Rob Fuller drove our client Gary’s S30 with the Datsunworks KN20 twincam cylinder head. Supporting the 3.1L engine are our Z Car Garage Big-Brakes, Z Car Garage CV Axles, Jenvey ITB EFI with Haltech Elite management, Nissan 6-speed CD009s transmission and OS Giken 4.11 LSD.

 

While ZCG has performed many tests with the KN20 engine this was the first time we were able to do a 300-mile trip and really wring its neck. It just keeps getting better and better…watch the video below and turn those speakers up!

Datsunworks in action

Vince’s 1973 Datsun 240Z

 

Vince’s 1973 Datsun 240z is Enjoying The Ride with our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles.  He scored this Z from our friends at Bring a Trailer and regularly drives on rally events.

Mrs. Butters

 

Leading the caravan was yours truly in Mrs. Butters, our Series 1 shop 240z. This Series 1 S30 features a 3.2L with triple-Mikuni induction, Z Car Garage Big-Brakes, Z Car Garage CV Axles, ZCG Heat Shield, 6-speed transmission and full KW suspension (releasing soon).

Jim’s 1971 Datsun 240Z

 

Jim’s 1971 Datsun 240z is now sporting a Rebello 3.2L with triple-Mikuni carbs on a Harada intake, Recaro Specialist seats, CD009a 6-speed transmission, our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles!

 

Linda’s 1972 Datsun 240Z

Linda Williams drove her 1972 Datsun 240Z OMS Pace Car Duplicate. Z Car Garage revived this historically-significant Z from its slumber to make it a nice driver for Linda while retaining its survivor status. She loves driving it everywhere.

 

Henry’s supercharged Nissan 370Z

Henry drove his Stillen-supercharged 370Z. This was his first time attending a vintage rally and he had a blast! Henry recently visited ZCG for a re-tune and upgrades, making even more power stay tuned for an update! Rolling photo by Gregory Veizades:

 
 

Mr. C, a 1970 Datsun 240Z

Our guest Herbert P piloted  “Mr. C”, our stock, one-owner Series 1 Z. We put some 14″ Panasports on this time as the stock hubcaps have a habit of coming off during spirited driving!

 

Our morning caravan of cars enjoyed cruising up I-280 through the Golden Gate Bridge. Nothing beats driving with fellow Z car owners!

 

Tokyo is Calling before the Rally!

 

Our crew arrived at the rally start in San Rafael and it was already filled with fabulous J-Tin. BCR hosted a “social gathering” from 8-9am (usually 1 hr) so we could take in all the glorious cars. The vibe was tremendous, and as usual it went by too quickly. Let’s go through some of the highlights, with more photos in the gallery below!

 

Tom K’s Nissan Fairlady Z432 stunned the crowd. This rare, RHD gem is powered by the unicorn-status S20 engine:

 

I am always on the lookout for Nissans and Datsuns, and roadsters always get my attention. There were at least 8 in attendance including two genuine 1967 2000s. One of the most sought after Datsuns, these “half-year” models were introduced mid-1967 offering a 5-speed transmission and 150hp twin-Mikuni carb’d 2L engine…hot stuff for the era.


Ian’s SRL is #601 (out of ~1000 cars) and it was fully restored years ago by Les Cannaday in San Diego. Ian is meticulous about maintaining this car, but it is no garage queen. The (655) Off-white paint with red interior is one of my favorites. Yes, it even sports a factory Nissan hardtop with all the stainless trim!

 

Our client Erik drove his hot-rod R16 stroker-powered ’70. We dyno tuned this little beast recently, check it out HERE:

 
 

There were handful of Datsun 510s in wagon and sedan form. Our client Jay installed a set of our Z Car Garage CV Axles on his Green 510. Jay is a hardcore rally driver (just completing the Faultline 500) and also brought his mint wagon with family! Check out his sweet set of Devil Shadow wheels:

 
 

Our very own Nick F drove his 510 wagon and went full rally-style with intercoms:

 

Back to Z cars, and with many cool examples like this pair of S30s with classy Campagnolo and 432s-style wheels:

 

Our client Kevin’s Slicktop Z32 on WORK XD9 wheels and Stoptech brakes. A pair of clean Zenki Z31 300ZX, one LS-powered:

 

Leo’s Nissan Pulsar GTi-R

 

We were pleasantly surprised to see Leo and his Nissan Pulsar GTi-R at Tokyo Calling 2. This RHD, JDM hot-hatch is known as “Baby Godzilla”, sporting all-wheel drive and an SR20DET drivetrain. What’s wild is that this Pulsar used to be owned by our very own Gary at Z Car Garage! Leo purchased it back in 2017 and drove it all the way from Reno, NV.

 

Leo is an avid Pulsar fan having owned several and he really kept this one in pristine condition. He added a few upgrades including Stoptech Big-Brakes. He ven kept the Z Car Garage license plate frame!

 

A pair of S13 240SXs:

 

It was great to see our R32 Skyline clients Mike’s R32 (TE37 wheels), Miles (Rays wheels) and Kurt W. (in his GC8 Subaru) and . All will be getting zcarblog udpates:

 

So many cool cars please check the gallery for more photos! Next, let’s check out some non-Nissan/Datsun action…

Kei Classics

Autozam AZ-1 and Suzuki Cappuchino mesmerizing the crowd with their size and neat features:

 

Honda

 

Honda was well-represented including late model DC2 Integras and S2000s. A few NSXs, CRXs and EF/EG hatches rounded out the display:

Toyota

 

Supra (A60 and A80) and even first gen MR2s, turbocharged Beams-powered Celica and AE86s!

   
 

Enjoy this walk-around of the pre-rally social hour at Tokyo Calling 2:

 

Trucks and Vans

Let’s not forget the Japanese classic trucks and vans!

 

The wildest car I found was this Nissan Leaf with motorcycle engine:

 

Rally On!

The rally started at 9am and I was tasked with leading our group. There was no cell phone reception but I was armed with a turn-by-turn rallye printout. I enjoyed hustling Mrs. Butters through the backroads:

 

One of the perks of BCR events is their team of professional photographers at various stages capturing epic rolling and detail shots so people can focus on enjoying the drive. I encourage you to visit each of these photographer’s photo albums to see shots of your rides: Alex Nibyt, Gregory Veizades, Everett Lederer, and Zack Hubbell.

  
 

Arriving at Point Reyes was another opportunity to see cars I missed at the starting point. Folks took a snack/coffee break here in the quaint town. I was just admiring each vintage ride cruise by…like this Nissan Figaro!

 

Henry’s 370Z and an FD RX-7

 
 

After chatting we resumed the rally. This final stage was my favorite with winding roads going through Petaluma. This is where the KW Suspension, ZCG Big-Brakes and 6-speed transmission in Mrs. Butters really shine. Every gear shift, squeeze of the throttle and confidence of the brakes makes for a sublime driving experience.

 
 

The rally concluded in Tomales. Total mileage for our San Jose crew thus far was 200 miles. BCR arranged for lunch at William Tell House as their clever motto is #DoneByNoon. The intersection here was yet another car show with J-Tin everywhere. It was a superb venue to enjoy cool cars and great company.

 
 

Our client Kevin’s Slicktop Z32

 

People got a kick out of the Behemoth:

 

Thanks BCR!

 

Many thanks to the organizers, we had a blast and I urge you to register for their next event, especially if you are in the South Bay area like me and want to see what driving bliss lies North.  Here are a few thoughts from Rob re-capping the Tokyo Calling 2 event:

“Loved TC2 and my favorite part is connecting with people, seeing their passion and all the other cool cars…I’m a huge Miata fan and NA/NBs were out in full force. Subaru XT…I really wanted one as a kid. Little fun fact…that rear end bolts into a Datsun 510. The Leaf with motorcycle engine was wild. Great to see our clients also on the drive. Got to see Leo and get reunited with the GTi-R, chat with Mike Young…”

“…Such a proud feeling of driving up 280 through the city and looking over to see Linda Wiliams in the OMS Pace Car, Vince S and Jim and Herb driving Mr.C. and Alex in his Sunny. The amount of community we have is tremendous. Loved how organized BCR is, so well thought out. The last 20+ years of my life I’ve been doing car meets/car adventures…the BCR guys got it down….from the registration stickers to rally directions. Little things like making sure there is enough room for folks at the meetup points…or always having clean restrooms available…these are details between enjoying yourself in a vintage car or not. The roads were incredible and scenery unreal. Sounds of L-series everywhere! Cant wait for next Tokyo Calling.”

The Drive Home

Our adventure was not over as we had to travel another 100 miles South to the shop. We caravanned back, traveling through the iconic Golden Gate Bridge and through San Francisco. I’m sure traffic had a field day with our group of Datsuns/Nissans:

 
At the shop, Rob gave everyone rides in the Datsunworks-powered Behemoth. It was fun to see the permanent smiles on passengers’ faces after returning:


After a full day of driving Mr. C, our stock Series 1 240Z,  we gave Herbert the keys to take Butters out for spin:

   
 

Thank you to all of the Z Car Garage clients that made the journey with us. Huge thanks to BCR for extending their hospitality to our crew, everyone was thrilled. Here’s to the next rally and always, always #DoitInADatsun!

We had a great day test driving and tuning two Z Car Garage-built S30 sports cars. Here are a few brief details of each build followed by video with dyno runs and road testing. LONG LIVE THE Z!

James’ 1972 Datsun 240Z

 

James’s 1972 S30  At the heart of this beast is a turbocharged L-series managed by Haltech. Chassis upgrades include custom full-length subframe connectors, CD009a 6-speed transmission, KW Suspension, ZCG CV Axles and Big-Brake Kit (328mm) behind RS-8 wheels restored by Love20bee. Larry Chen featured James’s Z on this episode of Hoonigan Autofocus. Inside, a stack instrument cluster was integrated into the gauge pod, viewed from leather Recaro Pole Position seats:

  
 

Recent upgrades to “Medusa” include a new tubular exhaust manifold, intake manifold and down-pipe from from ProtunerZ. We will have more installation photos and dyno results coming soon to zcarblog.com!

 

Gary’s 1971 Datsun 240Z

 

Z Car Garage is excited to collaborate with Datsunworks and develop their brilliant KN20 dual-overhead cam (DOHC) cylinder head designed for the Nissan inline-6 L-Series engine. This is a Honda K-series derived cylinder head with superior flow rates and modern valvetrain components effectively transforming your SOHC L-series into a high-revving DOHC engine. This KN20 is serial #SN10 and it has been installed into our long-time client Gary’s Datsun 240Z, affectionately named the “Behemoth”.

 
 

Here are few details on the powertrain setup for this Z:

-Rebello 3.1L Engine

-KN20 Cylinder head SN10 (but the performance level goes to 11)

-Induction type: Jenvey ITB EFI with Injector Dynamics injectors

-Engine management: Haltech Elite 750

-Header: Equal-length, custom fabricated by RacecraftNW

-Transmission: Nissan CD009a

-Rear Diff: R180 4.11 OS Giken LSD

 

L-Series Music

Rob took me for a spin in both cars. It was exhilarating. Volume UP and Enjoy!

We have installed the Datsunworks head into our client Gary’s Datsun 240Z (affectionately called the “Behemoth”) and it is currently in the tuning/testing stage. In conservative tune it made 350hp/248tq at the wheels. Recently we joined photographer Naveed Yousufzai at a photoshoot for full feature on Marqued.com. Check out the story and amazing photos by Naveed with amazing shots at Marqued HERE.

 

The photo shoot left us breathless and we really appreciate how the small details are captured like the Behmoth’s integrated roll cage, Recaro seats, 6-speed shift knob and 10krpm tach…check out the feature!

 

This video shows behind the scenes action of the photoshoot for Marqued.com. I tried to capture the incredible induction sound the KN20 creates. For the first time we cruised on the freeway together with the Behemoth…it was the “trifecta” with 240Z, 510 and Datsun Roadster. Turn up those speakers and enjoy!

TUNING: Two L-Series powered Datsun 240Z cars on the dyno

Filed under: 240z,Datsunworks,Performance
by Alvin G @ 5:10 pm on January 11, 2022

 

Last Friday we made some glorious L-Series music with two of our client’s Datsun 240Z cars. Gary’s Datsun 240Z, affectionately named the “Behemoth” has accumulated some mileage on the Datsunworks KN20 cylinder head and the dyno confirmed the same power level.

 

Khang’s 1973 Datsun 240Z was completed in October and he returned with 1,000 miles on the 3.2L L-Series. We adjusted the valves and double-checked power levels.

 

Happy to see both builds healthy and confirm power output. Enjoy the music from the both L-Series engines, sporting Jenvey ITB EFI managed by Haltech 750 Elite ECUs backed by the CD009a Six-Speed transmission. LONG LIVE THE Z!
